Progress M-14M went to the graveyard of spaceships

April 19 undocked from the International Space Station (ISS), the space truck "Progress M-14M", which during the nine days of the experiment was "Radar-Progress", received the command to brake and went to his last journey to the waters of the Pacific Ocean through the dense layers atmosphere of the Earth, told RIA Novosti the Control Center in Moscow (MCC).

"The engines are included in the truck braking 17.46 MSK. Expected unburned in the dense atmosphere of the Earth ship fragments splashed down in 18.39 MSK on so-called" graveyard "spacecraft in unnavigable Pacific" — a spokesman said.

MCC representative reminded that from 19 to 28 April in the truck were several series of physical experiments "Radar-Progress."

"This study was designed to determine the spatial and temporal dependence of the density, temperature, ionic composition of local inhomogeneities of the ionosphere resulting from the engines of" Progress "- said the representative of the MCC.

Location engine emission products during the experiments performed with the help of a unique located near Irkutsk Incoherent Scatter Radar (HP). With it you can get information about the electron density, electron and ion temperature, and ionic composition of the drift velocity in the altitude range of 100 to 1000 kilometers.

HF radars — complicated and expensive installation, which the world's only nine. The obtained experimental data are the basis for a wide range of studies on solar-terrestrial physics, including major international project Global Change, CEDAR, STEP.

Irkutsk incoherent scatter radar is located 120 kilometers north-east of Irkutsk. HP is based on a radar system "Dnepr", is a monostatic pulse radar with a frequency scanning and owned by the Institute of Solar-Terrestrial Physics, Irkutsk Branch of RAS.
